Wiring Considerations
There are several I/O interfaces use a plug-in screw terminal block for
the interface between I/O modules and field devices.
The following information must be considered when connecting
electrical devices to I/O modules.
1. The terminal block accepts wires from 0.5 mm to 2.5 mm.
2. Always use a continuous length of wire. Do not combine wires to
make them longer.
3. Use the shortest possible wire length.
4. Use wire trays for routing where possible.
5. Avoid running wires near high-energy wiring.
6. Avoid running input wiring in close proximity to output wiring where
possible.
7. Avoid creating sharp bends in the wires.
